2 Sheets-Sheet 2 Inventor Mud April 27, 1937. E. E. LONG REVOLVINGCUTTING DEVICE Filed March 31, 1936 By @zm Patented Apr. 27, 1937 UNITEDSTATES PATENT OFFICE 2 Claims.

My invention relates generally to an attachment for a grain divide boardfor cutting off the grain as it is pushed onto the platform of thecombine by the grain reel, so that the grain on the platform is freed togo into the threshing part of the combine, and an important object of myinvention is to provide a simple and efficient arrangement of thecharacter indicated whereby the operation of the combine is greatlyfacilitated and made more efiicient.

Another important object of my invention is to provide an attachment ofthe character indicated which can be easily and inexpensivelyincorporated in standard types of combines.

Other important objects of my invention will be apparent from a readingof the following description in connection with the drawings, whereinfor purposes of illustration I have shown a preferred embodiment of myinvention.

In the drawings:-

Figure 1 is a general side elevational view showing a combine reel indriving relation to the rotary cutter of the present invention.

Figure 2 is a top plan view of Figure 1.

Figure 3 is a horizontal sectional View taken through the rotary cutterand showing the horizontal cutting blade and guard in top plan.

Referring in detail to the drawings, the numeral refers generally to theend portion of the reel of the combine which is partly supported by thedeclining bar 3 and has on its axle 1 the sprocket wheel 3 over which istrained the sprocket chain 9 which sprocket chain is trained over asmall sprocket wheel ID on an axle H which has fixed thereto the largersprocket wheel l2 over which is trained the sprocket chain l3 which isalso trained over the small sprocket wheel I4 which is fixed to the axleIE on which is also the rotary cutter I6.

Pivotally connected to the axle I5 is the tightener and supporting barll and also the tightening and supporting bar l8 on which is slidablymounted the chain tightener sprocket 19 which is adjustable in the slot20. A bolt 2! in a slot 22 in the upper end of the bar 18 connects withthe bar 6. A bolt 23 in the slot 24 in the left hand end of the bar lladjustably connects the bar H with the vertical frame member 25 whichhas a bolt 26 which secures the bar 6 at the left hand end thereof.

The idler sprocket I9 which is utilized as a sprocket tightener, engagesthe underside of the lower flight of the sprocket chain 9.

A tightener bar 2! carries the axle [5 at its lower end and has a slot28 in its upper end which is slidable on the axle II and adjustablysecured by a wing nut 21 threaded in the end of the axle II.

The lower end of the frame member 25 is fastened in conjunction with thecombine platform 39 and also attached to the vertical member 25 by thebolt 31 is the knife carrying bar 32 which has on its laterally outwardside the cutting knife 33. Attached at the forward end of the knife bybolts or rivets 3:2 traversing the bar 32 and having a laterallyoutwardly deflected portion 35 is the guard which is generallydesignated 36 and which extends along the laterally outer side of therotary cutter E6, the rotary cutter having its peripheral edge extendingbetween the bar 32 with its cutter 33; and the guard 35.

The various bars described may be of strap iron and due to theirarrangement and combination can be adjusted to tighten the varioussprocket chains for efficient operation and to take up wear.

As the grain is picked up and cut oif by the cutter knife it is thenpushed onto the platform 30 by the grain reel 5. In accordance with thepresent invention, as the grain comes in contact with the rotatingcutting disk i6 and the cutting blade 33 on the cross bar 32, the grainwhich extends out over the end of the platform, will be cut off, and thegrain on the platform made free to travel without impediment into thethreshing part of the machine. The cutter of the invention is used atthe outer end of the platform and positively prevents lodging of thegrain on the end of the platform.

The rotary cutter I6 is a disk with teeth 36 on its periphery which aresegmental in shape and which in conjunction with the guard 35 and thecutter 33 on the bar 32, positively shear and cut the grain overhangingthe end of the platform.

Although I have shown and described herein a preferred embodiment of myinvention, it is to be definitely understood that I do not desire tolimit the application of the invention thereto, and any change orchanges may be made in the materials, and in the structure andarrangement of the parts, within the spirit of the invention and thescope of the subjoined claims.

What is claimed is:

1. In combination with a combine having a platform and a reel, a knifeat the outer end of the platform, a guard in spaced parallelism with theknife, and rotary cutter means adjustably supported adjacent the outerend of the platform and working between the knife and the guard inshearing relation to said knife for cutting off grain bridging the knifeand the guard, and drive means connecting the reel and the rotarycutter. 2. In combination with a combine having a platform and a reel, ahorizontal knife at the 5 outer end of the platform, a guard in spacedparallelism with the knife, and rotary, cutter means adjustablysupported adjacent the outer end of the platform and Working between theknife and the guard in shearing relation to said knife for cutting offgrain bridging the knife and the guard, and drive means connecting thereel and the rotary cutter, means supporting said horizontal knife and aguard thereon extending along the laterally outward side of the rotarycutter.
